Filed: 1936-03-19
Abstract: 475,729. Electricity supply. BLUMLEIN, A. D. March 19, 1936, No. 8295. [Class 38 (iv)] Systems depending on two or more machines ; turning generators in parallel.-In an arrangement for preventing voltage variations of an A.C. supply source affecting the voltage at a supply point, a synchronous electric machine A1 is connected through an inductive impedance element s1 to the source of supply M, N and through a second inductive impedance element s2 to the supply point L, the two inductive impedances sl, s2 being inductively coupled to each other so that the required effect is obtained. The supply point may be connected to a load or to a second source of A.C. associated with a feeder supplying a load. The ratio of the impedances of the impedance elements is also equal to the inverse ratio of the squares of the normal mean or full-load currents which flow through them in operation. The synchronous machine A1 may be a motor or a generator and the impedance elements s1, s2 may be constituted by a tapped choke C, the two parts ab and bc of which are arranged in a series aiding sense. The mutual coupling between the impedances is arranged to have an inductive component,which is substantially equal to the armature reactance or to the armature reactance together with the armature reaction, or is intermediate between these values. so as to obtain compensation for impulsive voltage variations or slow variations or for a mean, between the two types of variation. The internal impedance of the machine A1 is shown by an equivalent series impedance z in Fig. 1. The arrangement may be applied to polyphase A.C. systems and the Specification describes its application to systems in which a three phase machine A1 is star-connected and deltaconnected, three chokes such as C being used in the star-connected system and six in the delta-connected system. The arrangement and design of the chokes is similar to that described in Specification 461,004. Principles for the design of a choke C for the case shown in Fig. 1, in which the machine A1 supplies power to the system, are given in the Specification. The invention is also described as applied to a system comprising , five poly-phase power stations A, B, C, D, E, Fig. 6, station A having three bus-bars 11, 12, 13 for each phase. The bus-bar 13 of each phase is connected to machines or groups of machines 14 and 15 through part of chokes 17 and 19 and the busbars 11, 12 may be connected directly to the machines 14, 15 through the other part of the chokes 17, 19. As shown, however, chokes 16, 18 are provided to reduce coupling between the bus-bars 11, 12. At the other stations B-E only one machine such as 23 is shown at each point. Feeders L are connected to loads. Two loads L1, L2 are isolated from each other by a tight coupled choke 20 constructed and arranged as set forth in Specification 461,004. By this means supply points L and feeders are interconnected with sources of A.C. without fluctuations in voltage in the sources affecting the loads or feeders.

Title: Improved process for gelatinizing or solidifying mineral oils and oils produced by the same
Filed: 1930-03-18
Abstract: Mineral oils are gelatinized to produce lubricants of determined viscosity and consistency or a basis for toilet preparations by adding 6-9 per cent of a soap and heating to above 350 DEG  F. but not above 500 DEG  F.  The oil may first be heated to about 250 DEG F. to remove water.  The solidified oil may be melted up with more oil to produce a product of less consistency. Graphite or other solid lubricant may be added.  In an example, 1,5 lb. of soft soap made from castor, rape seed or cottonseed oil is stirred into 20 lb. of axle oil preliminarily heated to 212-250 DEG  F., and the temperature is raised to 450 DEG  F. until frothing ceases.
